- Examples of what pupils should
know and be able to do - Probing questions
- What if pupils find
this a barrier?
What if pupils find this a barrier?
Show the data handling cycle. Explain that this is the planning part of the cycle.
Have available the data collection sheets from:
- Interacting with mathematics – handling data (DfES 0220/2002) Phase 1
Discuss the appropriateness of these with pupils and allow them to suggest
improvements. Ideas can be found in:
- Securing progression in Handling Data (DfES 0658-2003G): Planning to test a hypothesis
- Interacting with Mathematics Handling Data (DfES 0220/2002) Phase 2
